Phalaenopsis plant named &#34;Phal. Younghome Venus&#34;

ABSTRACT

Phal. Younghome Venus has not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in environment such as temperature and light intensity, without however, any change in genotype. In the following description, color reference are made to The Royal Horticultural Society (R.H.S.) Colour Chart, 2007, fifth editon, except where terms of ordinary dictionary significance are used. 
     Dtps. Younghome Venus used for aforementioned photographs and following detailed botanical description were 11 months old and grown in 12 cm containers in Pingtung, Taiwan, in a controlled green house with day temperature about 26˜29° C., night temperature about 18˜20° C., and light level about 15,000˜20,000 lux. The photographs and detailed botanical description were taken during the winter.

FIELD OF THE INVENTION

Botanical classification: Phalaenopsis

Variety denomination: Phal. Younghome Venus

BACKGROUND OF THE INVENTION

The present invention comprises a new and distinct cultivar of Phalaenopsis Orchid, and hereinafter referred to by the cultivar name, Phal. Younghome Venus.

The new cultivar is a product of a planned breeding program conducted by the Inventor in Pingtung, Taiwan. The objustive of the breeding program is to create new uniform pot-type Phalaenopsis Orchid cultivars having attractive flower coloration.

Asexual propagation by tissue culture in a laboratory in Pingtung, Taiwan has been used to increase the number of plants for evaluation and has demonstrated that the unique combination of characteristics as herein disclosed for the new Phalaenopsis Orchid are firmly fixed and are retained through successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be basic characteristics of new cultivar which in combination distinguish this Phalaenopsis Orchid as a new and distinct cultivar:

-   -   1. White flower with red purple color shaded around the column.     -   2. Freely flowering habit.     -   3. Upright, freely branching and sturdy flowering stem.     -   4. Strong growth ability and disease resistance.

Plants of the new cultivar differ primarily from plants of the parent cultivars in flower color. Plants of Phal. Younghome Venus can be compared to the Phal. Sogo Yukidian (not patented) in the following characteristics:

-   -   1. Plants of the new Phalaenopsis orchid are smaller than plants         of the cultivar Phal. Sogo Yukidian.     -   2. Plants of the new Phalaenopsis orchid have shorter spikes         than plants of the cultivar Phal. Sogo Yukidian.     -   3. Plants of the new Phalaenopsis orchid have smaller flower         size than plants of the cultivar Phal. Sogo Yukidian.     -   4. The petals for plants of the new Phalaenopsis orchid are         white and red purple around the column, while plants of the         cultivar Phal. Sogo Yukidian is white.     -   5. The new Phalaenopsis orchid have orange labellum and plants         of the cultivar Phal. Sogo Yukidian is yellow.
